PEBBLE BEACH, California (Reuters) — Phil Mickelson’s bid for an elusive first US Open title and Tiger Woods’ desperate search for greater consistency have dominated the build-up to Thursday’s opening round at Pebble Beach.

While several other compelling storylines have conspired to make the second major of the year among the most intriguing in a long while, most eyes will be fixed on the game’s leading players.

World number two Mickelson and top-ranked Woods, both born in California, know Pebble Beach Golf Links very well and have produced winning form on the spectacular coastal layout.

Left-hander Mickelson has clinched the PGA Tour’s Pebble Beach National Pro-Am three times while Woods delivered one of the best golfing displays ever at the 2000 US Open when he stormed to victory by an astonishing 15 strokes.

“It was the greatest performance I've ever seen in the game, to shoot 12-under,” Mickelson told reporters while preparing for the first round. “That was the best ball-striking and the best putting tournament that’s ever been performed in my opinion.”

Much has changed, however, since Woods set record benchmarks in the game which have yet to be eclipsed.

Although he has won 14 major titles to trail only Jack Nicklaus (18) in the all-time standings, his golfing stock plummeted following his stunning fall from grace at the end of last year.

Woods quit the game for five months amid tawdry revelations of marital infidelities and has fallen well short of his own lofty standards since returning to the PGA Tour at the US Masters in April.

He has played in only four events on the US circuit while battling neck pain and has parted ways with his long-time swing coach Hank Haney but believes he is now close to his best based on his practice sessions in recent weeks.

“As far as my game, I'm very excited about how it’s progressed,” said Woods, who has been paired with British world number three Lee Westwood and double US Open champion Ernie Els of South Africa for the first two rounds at Pebble Beach.

“The more time I've been able to practise and play, it’s starting to solidify and I'm actually really excited to tee it up on Thursday.”

While major question marks hover over Woods’ likely form, US Masters champion Mickelson is viewed by many of his peers and several leading bookmakers as the tournament favorite.

Despite several agonizingly close calls over the years and five runner-up finishes in his last 11 US Open starts, the short-game magician has never won his national championship.
